Objective ToinvestigatethepatternsofbrainactivityabnormalitiesinpatientswithParkinson’sdisease(PD)with freezingofgait(FOG),andtoexploretheneuropathologicalmechanismofFOG.Methods Resting-statefunctionalMRI(rs-fMRI) scanswereobtainedfrom31PDpatientsand16healthycontrols(HCs).Accordingtothefreezingofgaitquestionnaire(FOG-Q),31 PDpatientsweredividedinto15PDFOG(+)and16PDFOG(-).ANCOVAandPost-Hocttestwereperformedtoassessinter groupdifferenceofbrainactivityabnormalitybasedonregionalhomogeneity.Results ComparedtoHCs,PDFOG(+)showeddecreased ReHointheleftinferiortemporalgyrus,rightlingual,bilateralfusiform,rightoccipitalgyrus,rightcalcarine,andrightcerebellum, whileincreasedReHointherightmiddlefrontalgyrus,rightsuperiorfrontalgyrus,rightprecentralgyrus,andrightsupplementary motorarea(SMA).ComparedtoPDFOG(-),PDFOG(+)exhibitedincreasedReHointherightprecentralgyrus,rightmiddle frontalgyrus,rightinferiorfrontalgyrus,andrightSMA,whiledecreasedReHoinleftfusiform.Conclusion Thisstudysuggests thatFOGinPDisassociatedwithabnormalitiesincerebellum,frontallobeandvisualnetwork,whichishelpfultounderstandthe neuralmechanismsunderlyingFOGinPD.
